RSOM-31
|
A significant improvement in quality of life was observed, following IGS
compared with ESS, in the subgroups nasal symptoms, ear symptoms,
general symptoms and practical problems.
|
The improvement in overall quality of life six months post-ESS appeared
to be further enhanced when computer assistance was added to endoscopic
sinus surgery.

Sphenoid sinus penetration
|
IGS: 83 out of 91 sphenoid sinuses were successfully opened. ESS: 35 out of 51 sphenoid sinuses were successfully opened. |
IGS was a beneficial procedure for opening the sphenoid sinus,
especially in the revision cases.

IGS: 35 ESS: 35 | Navigation Accuracy, Set up time Gain in security for the surgeon, Complications | IGS: two patients had complications. ESS: six patients had complications. Gain in safety (1-5) with IGS: average 4.4 (±0.25) Additional effort with IGS (1-3): Average 1.8 (±0.75). |
The question, whether using IGS a higher security can be reached with a
lower complication rate cannot be answered so far. It is remarkable the
subjective assessment of the surgeon who claim to have experienced a
security gain with IGS.

Operating room time
System accuracy Blood loss Complication |
IGS: No complications. Blood loss: 566.67 (± 62.23) Operating room time: 165.68 (± 6.55) ESS: One complication (orbital swelling) Blood loss: 636.33 (± 72.59) Operating room time: 163.33 (± 5.43) Accuracy within 2 mm. |
IGS improves the confidence of surgeons in reaching difficult areas
safely leading to thorough disease clearance, especially in revision
cases, altered anatomy, or extensive disease cases. The additional time
taken for device setup and registration was effectively overcome by the
reduced intraoperative time. Blood loss and complications did not differ
significantly with or without IGS.

Postoperative drained paranasal sinuses
|
IGS: two missed paranasal sinuses / three complications ESS: five missed paranasal sinuses/ three complications. |
IGS should have an assured place in training and teaching for paranasal
sinus operations. Even if this new technology means extra costs, it was
welcomed by all study participants (surgeons and patients).

IGS: 150 ESS: 150 | Operating room time Successful sphenoidal sinusotomy Patient subjective assessment | Incision-suture time: average 10.1 min less with IGS. Perioperative preparation time: 7 min on average more with IGS. Successful sinusotomy: IGS: 31/31 ESS: 9/40. Patient assessment: general feeling of well-being 73% IGS / 69% ESS; Minimal improvement, no improvement or worsening 16% IGS /30% ESS; would have the surgery again: 96% IGS/85% ESS. |
The advantages of the examined navigation system compared to the gold
standard of ESS are proven. Navigation assistance led to reduced
intraoperative time, increased postoperative results, and lowered the
workload of the surgeons.
